Fish transportation is a regular farming and experimental practice that mainly results in stress conditions that may extend to induce a high mortality rate. In the present experimental simulation, Oreochromis niloticus were transported for 2 h and maintained for another 6 h in transportation containers to assess the effect of tranquilization with tricaine methanesulfonate (MS-222) and/or the addition of iodine on mortality rate and restoring the normal physiological functions. Experimental fish were divided into four groups: group 1 (control) was transported in farm water without MS-222 or iodine, group (2) was transported in farm water supplemented with 40 mg/L of MS-222, fish in group (3) were transported in farm water supplemented with 40 mg/L of MS-222 + 10 ppm iodine, and fish in group (4) were transported in farm water containing 10 ppm iodine. Blood samples were collected for the determination of serum cortisol and glucose, while skin mucus was collected for assaying lysozyme, peroxidase and antibacterial activity; cumulative mortality rate; and food reflexes which were assessed at 0 h, 1 h, 6 h, 48 h, 7 days and 14 days post 2 h transportation. The results indicated that fish tranquilization with MS-222 and/or treatment with iodine mitigated the stress condition associated with transportation and accelerate restoration of the normal physiological and immunological status. So, it was recommended to use the MS-222 as a tranquillizer together with iodine as an antiseptic during transportation of O. niloticus.

“…In general, swimming activity and time required to exhaust fish were lower in more severely cold‐shocked juvenile Murray cod, silver perch and golden perch (Michie et al ., 2020b). Mottled mojarra ( Ulaema lefroyi Goode 1874) acclimatized to 24°C and acutely exposed to 20, 18 or 16°C for 1 h had higher likelihoods of equilibrium loss and reflex impairment over time at 18°C and especially at 16°C (Samson et al ., 2014). Trends in post‐exposure chases to exhaustion and movement during chases were less clear, with mojarra exposed to 16°C having longer chase times than fish at 18 or 20°C and more lines crossed than fish at 18°C (despite none of these treatments differing significantly from the 24°C control; Samson et al ., 2014).…”

Equilibrium loss and reflex impairment are often thought of as symptoms of chemical anaesthesia (Summerfelt & Smith, 1990) and also can occur following cold stress or other debilitating stressors such as toxicity (McKim et al ., 1987).…”

Temperature is critical in regulating virtually all biological functions in fish. Low temperature stress (cold shock/stress) is an often-overlooked challenge that many fish face as a result of both natural events and anthropogenic activities. In this study, we present an updated review of the cold shock literature based on a comprehensive literature search, following an initial review on the subject by M.R. Donaldson and colleagues, published in a 2008 volume of this journal. We focus on how knowledge on cold shock and fish has evolved over the past decade, describing advances in the understanding of the generalized stress response in fish under cold stress, what metrics may be used to quantify cold stress and what knowledge gaps remain to be addressed in future research. We also describe the relevance of cold shock as it pertains to environmental managers, policymakers and industry professionals, including practical applications of cold shock. Although substantial progress has been made in addressing some of the knowledge gaps identified a decade ago, other topics (e.g., population-level effects and interactions between primary, secondary and tertiary stress responses) have received little or no attention despite their significance to fish biology and thermal stress. Approaches using combinations of primary, secondary and tertiary stress responses are crucial as a research priority to better understand the mechanisms underlying cold shock responses, from short-term physiological changes to individual-and population-level effects, thereby providing researchers with better means of quantifying cold shock in laboratory and field settings.

“…Low thermal stress also reduces the cardiac performance in largemouth bass, Micropterus salmoides (Cooke et al, 2003), and sculpin, Myoxocephalus scorpius (Filatova, Abramochkin, & Shiels, 2019). Mottled mojarra, Eucinostomus lefroyi showed significant increases in ventilation rate and reflex impairment at 18 and 20°C compared to 24°C (Samson et al, 2014). Proteomic analysis showed that cardiac proteins increased significantly in eurythermal goby, Gillichthys mirabilis when exposed to 9 and 26°C from 19°C during a 28‐day thermal exposure (Jayasundara et al, 2015).…”

Climate change‐induced extreme temperature events are becoming more intense and frequent. For fish, temperature is the master abiotic factor that controls and limits fish development and physiology at all stages of aquaculture. Major physiological constraints at the individual level underpin changes in fish growth, hemato‐physiology, metabolism, immune and molecular stress responses to extreme temperature events. Extreme temperature impacts on fish vary among and within the diverse species depending on stress magnitude and associated factors. This review synthesizes the impacts of climate change‐induced extreme temperature events on neuroendocrine, oxidative, metabolic, osmotic, molecular, hemato‐biochemical, and immune responses in fish related to aquaculture. Besides, overall aspects of extreme temperature impacts on fish growth and reproduction are also discussed. Possible mitigation measures to maintain the fish's physiological fitness during extreme temperature events are also addressed. However, studies on the interactive effects of extreme temperature events with other associated environmental stressors are needed across a broader range of species to gain a better understanding of fish response and aquaculture performance during extreme temperature events. Moreover, for fish, studies on alternative species, development of stress‐tolerant strains, and the possibilities of nutritional mitigation measures as a potential option to combat extreme temperature stress are promising and should be pursued in future studies.
